Given numbers are 489, 961, 16, 636

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(489, 961) = 469929

GCD(489, 961) = ( 489 x 961 ) / 469929

= 489 / 961

= 489

Step2:

LCM(1, 16) = 16

GCD(1, 16) = ( 1 x 16 ) / 16

= 1 / 16

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 489, 961, 16, 636 is 1
